Protocol Lists Are Not Enough
Camera gateway pages often list RTSP, ONVIF, GB28181, RTMP, HLS, WebRTC, and SRT. Protocol support matters, but a gateway is useful only when it connects the full workflow: ingest, management, playback, recording, APIs, licensing, and diagnostics.
What to Check
| Dimension | Questions |
|---|---|
| Ingest | RTSP URLs, ONVIF discovery, NVRs, GB28181, existing streams |
| Browser playback | Plugin-free preview, low latency, multi-view, playback URLs |
| Recording | Schedules, indexes, time search, web replay |
| APIs | Channels, state, playback URLs, recording search, events |
| Deployment | LAN, private network, on-site server, offline licensing |
| Licensing | Clear input-channel licensing without hidden viewer metering |
| Operations | Logs, status, ports, services, license, and resource metrics |
StreamGate Positioning
StreamGate does not replace the customer business system. It handles on-site video access and exposes channels, playback URLs, recording information, and status through Web Console and APIs.
Evaluation Advice
Before purchase, test with real cameras, NVRs, GB28181 platforms, target servers, browsers, and API calls. Validate first-frame time, stability, recording replay, logs, and license behavior.
Do Not Evaluate by Protocol Names Alone
Two products may both claim RTSP, ONVIF, or GB28181 support, but differ greatly in batching, online status, sub-stream selection, reconnect behavior, recording search, browser playback, APIs, diagnostics, and licensing expansion. A single-channel playback test is not enough for site acceptance.
When a Gateway Fits Better
A gateway is usually the better choice when the project needs to manage many cameras, expose playback URLs to business systems, provide browser preview, record and replay video, interconnect with an upper GB28181 platform, or expose device status through APIs.
What to Validate Before Purchase
Use real cameras, real NVRs, the target network, and the target browser. Validate onboarding, preview, recording, replay, restart recovery, abnormal logs, port exposure, and license upgrade flow.
Selection Dimensions
Start with input sources: IPC, NVR, RTSP URL, ONVIF, GB28181, SRT backhaul, and existing streams. Then confirm output targets: browser viewers, display walls, business platforms, upper GB28181 platforms, or third-party clients.
Do Not Only Count Channels
Channel count is only the first sizing signal. Real capacity depends on bitrate, resolution, codec, recording, viewers, disk IO, network bandwidth, and server hardware. Validate with real devices and target bitrate.
Gateway vs Platform
A gateway solves ingest, management, playback, recording, distribution, and integration. A larger platform may also provide organization, maps, business alarms, workflows, and cross-region scheduling.
Before Purchase
Prepare one real IPC, one NVR or platform, and one business integration requirement. Validate discovery, stream pull, playback, recording, and APIs before scaling the decision to more models and more channels.
